Uea TPE VS Uea TPU

TPEʻO (Thermoplastic Elastomer) kahi mea Thermoplastic Elastomer (Thermoplastic Elastomer) me ka ikaika kiʻekiʻe, elasticity kiʻekiʻe, hoʻoheheʻe ʻia ʻana, ākea o nā noi, palekana i ke kaiapuni, ʻaʻohe mea ʻawahia a palekana, a maikaʻi loa ke kala.

TPUʻO (Thermoplastic Urethane), i ʻike ʻia ma ka ʻōlelo Kina ʻo Thermoplastic polyurethane elastomer, he ʻano TPE ia. ʻO TPU kahi ʻano mea polymer i haku ʻia me diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), macromolecular polyol a me ka mea hoʻolōʻihi kaulahao.

Ii. Nā ʻokoʻa ma waena o TPE a me TPU:

1. ʻOkoʻa o ke kaumaha kikoʻī:

TPE (0.89~1.3);

TPU (1.0~1.4);

2. ʻOkoʻa i ke kū'ē ʻana i ka aila

ʻO ke kūpaʻa o TPE i ka aila he ʻano paʻakikī, akā maikaʻi ka manaʻo, palupalu a laumania;

He kūpaʻa maikaʻi ko TPU i ka aila, ka hakakā lima ikaika a me ka laumania maikaʻi ʻole.

3. Nā ʻokoʻa o ke kū'ē ʻana i ka mahana:

TPE (-60 ℃ ~105 ℃);

TPU (-60 ℃ ~80 ℃);

4. Nā ʻokoʻa o ke kūpaʻa a me ke kūpaʻa ʻana i ka ʻaʻahu:

ʻOi aku ka maikaʻi o ka TPU i ke kūpaʻa a me ke kūpaʻa ʻana i ka ʻaʻahu ma mua o TPE.

5. Nā ʻokoʻa ma ka pae paʻakikī:

TPE (0~100A);

TPU(35~90A, 50~80D), ʻo ka paʻakikī maʻamau ka 80~95A. ʻAʻole i hoʻohana pinepine ʻia ka TPU me ka paʻakikī o 50~80D i ka hana. ʻO ka paʻakikī 35~75A TPU, ke kumukūʻai kiʻekiʻe o nā mea. Hōʻike ʻia ka TPU e ka ikaika kiʻekiʻe a me ke kūpaʻa maikaʻi o ka ʻaʻahu. ʻO nā ʻano nui: ka laulā o ka paʻakikī, a me ka hoʻonui ʻana o ka paʻakikī, mālama mau kāna huahana i ka elasticity maikaʻi a me ke kūpaʻa ʻana o ka ʻaʻahu, ka ikaika mechanical kiʻekiʻe, ke kūpaʻa anu maikaʻi loa, ka hana hana maikaʻi, ke kūpaʻa aila, ke kūpaʻa wai, ke kūpaʻa ʻōpala, hana hou maikaʻi.
